IMPROVEMENT IN FURNACES FOR MELTING GLASS.

Specification forming part of Letters Patent N0. 171,876, dated January 4, 1.876; application led September 30, 1875.

To all whom it may concern:

Be it known that I, NICHOLAS SNYDEE, of Pittsburg, Pennsylvania, have invented au Improved Furnace for Melting Glass, of which the following is a specification:

This invention relates to certain improvements in the construction of glass-furnaces, its object being to bring the flame from the burning fuel more thoroughly incontact with the whole exterior of the pots, for the purpose of economizing the fuel and more regularly and uniformly heating the said pots.

The glass-furnaces heretofore in use have usually been constructed with a series of ducs extending from the oven or chamber in which the pots are. located to tluesin the sides ofthe furnace, communicating with the stack of the same, for cz'irrying off the products of combustion. As thus constructed, the dames of the. burning fuel first pass upwardly to the dome, and then downwardly deflected, escaping through the bottom of the oven without being thoroughly carried around the pots, and failing to heat them effectively.

My invention is designed to obviate this defect; and it consists in constructing the ful'- nace with aseries of horizontal tlues, extending radially'from the inner wall ofthe oven opposite the breast of each pot to a series of short segmental tlues formed within the'body of the wallsof the oven, said segmental tlues communicating at each end with vertical ilues, which are formed in pairs within the walls of the furnace, and which extend to the top of the furnace, terminating in the stack.

lu the drawing, Figure l represents a view showing partly a vertical section and eleva tion of the oven of my improved furnace, and

- usual, the pots C being arranged in an annular row around the vsides of the same, with their mouths opposite the working-holes D, extending through the walls of the oven. Immediately opposite the breast of each pot, just under the opening or mouth of the same, I constructa shortv horizontal flue, E, extending radially into the body of'` the wall of the furnace, each intersecting a short horizontal segmental flue, F, formed Within the body of the wall. Each of said segmental flues communicates with two vertical lines, Gr, terminating at their upper ends above the dome in the smoke-stack.

As thus constructed, when the fire is builtf4 in the furnace the flames and burninggases from the fuel proceed upwardly from thebpening B, and, striking against the top of the same, are deflected downwardly toward the lines E, passing over and entirely' around the glass-pots, heating the same thoroughly on all sides. From thence the products of com bustion pass into the segmental tlues F, and

then into the flues G, and ont of the furnace through the smoke-stack.

As the lines G are common tothe ordinary glass-furnaces in which the 'serve to connect the ilues below the bed of the oven with the smoke-stack, it is evident that an ordinary furnace may b e readily altered and improved to correspond with myinven'tion, by filling up -the tlues below the bed, and constructing thev connecting with the ues G, substantially as described.

vl/Vitness my hand this 27th day of September, 1875.'
